Asking user to confirm they are still attending the meeting

My english ain't the best so I'm asking y'all how I can word my notifications.

Prior to a meeting starting, about an hour before, I want to send out a notification to all the attendees asking whether or not they're still attending. If they are attending, that's cool. If they changed their mind, this will let me let the host know that one of the people won't be coming.

Here's my rough draft for the push notification title and message that I want to show to attendees:

Title: Upcoming Event - {event.name}

Message: Confirm if you will be attending this event at {event.startsAt}

This reads pretty bland and boring to me, and I'm wondering if there's a better way to construct this title/message.
